Application tiled August 23, 1915. Serielle. 46,867.

To all whom it may concern.'

Be it known that l. RAYMOND W. DULL, a citizen of the United States of America, and resident of 133 SoutlrSixth street, La Grange, Illinois` have invented a certain new and useful Improvement in Separators, of which the following is a specification.

This is an improvement on the construction disclosed in my prior Patent No. 1,155,473, patented Oct. 5, 1915.

My invention relates, therefore, to separators of that kind in which a receptacle is supported to move u and down, and in which the lower end o the receptacle is pro vided with a downwardly opening valve, whereby sand and water discharged into the receptacle will be separated by the overilow of the water at the top, and by the automatic discharge of the sand at the lower end of the receptacle, a full load in the receptacle serving| automatically to open the .valve at the lower end thereof.

The ob'ect of my invention is to provide novel an improved means for supporting the receptacle and its valve, und for thereby rendering the same more certain in operation, as Well'as more satisfactory in various Another object is to prevent the formation of an opening in the sand around the valve rod and to thereby prevent the water from discharging through the valve opening at thel bottom of the receptacle.

Another object is to provide means,or discharging the sand and water into the receptacle of the separator in such a manner that the contents will not boil 0r become agitated to the extent that thesand will escape from the top of the receptacle with the water; and whereby the sand will thus be caused to settle practically as soon` as it enters the receptacle, allowing the water to discharge freely and alone from the spout provided for that purpose at the. top of the receptacle.

To the foregoing and other useful ends my invention consists in matters hereinafter set forth and claimed.

ln the accompanying drawings- Figure 1 is a side elevation of an automatic sand and water separator embodying the principles of my invention. the lower end of the receptacle being shown in section to illustrate the construction and arrangement ot' the downwardly opening valve.

Fig. 2 is a vertical transverse section on line 2*-2 in Fig. 1.

Fig. 3 is a. horizontal cross section on line 33 in Fig. 1.

As thus illustrated, my invention co1nprises a body frame A composed of horizontal beams spaced apart and connected together by a cross beam a in a manner that will be readily understood. The receptacle B is shaped like an inverted cone, being tapered downwardly, and is provided at its sides with brackets b in which are removably held the lower end portions of the rods (l which serve as supporting hangers for the receptacle. The upper end of each rod C is provided with a wedgeshapcd block c removably held in place by a nut screwed on the upper end of said rod. An angle iron D is secured crosswise of the beams at one side of the receptacle, and a similar angle iron is secured erosswise of the beams at the other side of the receptacle, as shown more clearly in Fig. 2, and a fnlcrnm plate cl is secured in a vertical plane to the face of each angle iron, these two plates being arranged in line with each other. Short levers E are provided with seats e at their ends, and on their under sides, these seats engaging the upper edges of the ,plates d, whereb the latter serve as fulcrums. These levers are also provided with u per seats F for the lower edges of the we(v ges c, and have open ings f through which the rods C extend verticallynthese openings being large enough `"to afford each rod some lateral movement therein. vAt their other ends the levers E are provided with lower seats G which rest` upon the upper edges of transverse plates g which are fixed between the angle irons H. A inidge plate h is fixed between the angle irons and the hanger or link thus formed to support the distal ends of the leve-rs E is adapted to rest on the parallel beams of the frame when the receptacle moves down ward. The plate L has an opening I therein for accommodating rthe long lever J, and the upper edge of this opening rests in=the seat. j mounted on top of said lever. The cross beam a has a fulcrum K which engages the seat k on the bottom of the lever J and the latter has an adjustable counter-balancing weight L of any suitable character mounted upon the free or distal end portion thereof. The other end ot' this lever .I is pivoted at l to the upper end of the vertically disposed rod M `which extends downward through the receptacle at the renter thereot' und which is provided at its lower end with a movable vulve member 11:. the latter being cone shaped and adapted to engage the seat N provided around the edge of the opening formed at the lower end of the receptacle. ln this way the valve closes by upward movement and opens by downward movement and the movable valve member is supported by the said rod directly on the connterbalancing lever. .X spout provides for the overflow of the water from the top of the receptacle.

The operation is as follows: Sand and water are discharged into the top of the receptacle and when the latter is fully loaded iL raises the weight L and moves downward. 'l'luproportions are such, and the relative arrangement ot' the pivotal points and fulcrums is such, that the rod M moves downrfard a little faster than the receptacle. Consequently, and by the time the angle irons H engage the tops of the beams A, the valve member m is some distance below the valve seat on the lower end of the receptacle, and thus the sand is automatically discharged. As soon as the desired discharge has been Iaccomplished, and before the water remaining in the receptacle can escape at the lower end of the latter, the counterbalancing weight L again raises the receptacle and thereby closes the valve. Thus the water is taken off through the spout 0 and the sand is periodically disrharged through the bottom ofthe receptacle. As previously stated, the plate h and the fulcrum plates g and the angle irons H together form-a link between the levers E and the lever J and suspend the weight of the receptacle on the said counterbalancing lever. Angle irons P can be Vprovided at the top of the receptacle, and arranged to extend crosswise thereof, and a plate p may beA secured to the tops of these angle irons and provided with an opening for the rod M, whereby the latter is guided in a proper manner and held approximately at the cen- 1er of the receptacle during the up and down movements of the latter. With this arrangement the rod M reciprocates relative to the receptacle during t e operation of openingand closing the valve.

The rod M extends downward through the load in the receptacle, and to prevent the sand from packing together and formin;r an opening around this rod, through which opening the water would escape downward, thus holding the receptacle in its lowered sition, a spider Q is provided, the arms op this spider being suitably secured to the walls of the receptacle, and the r-ontral portion 7 surrounding the rod M und forming :i guido therefor and compellinier the sand to pass outward and downward between the arms of the spider. In

this way. the proper operation of the appa-- ratus is insured. whereas without this featu re thi-re would be some danger of an opening forming in the sand around the rod M and a continuous discharge of water through this opening.

A dam or battle plate l extends in a vertical plane across the top of the receptacle, inside the upper portion thereof, thereby preventing the sand from washing through and being discharged from the spout (i with the water. This baille plate is supported in any suitable manner at its ends, and the water and sand are discharged into said rc ceptacle and against said battle plate. The sand sinks or precipitates to the bottom of the receptacle, and the water Hows downward and below' the lower edge of said balHe plate and then rises and discharges from the spout O, in a manner that will'he readily understood.

As a. mattei' of further and special improvement the water and sand are conveyed to the receptacle by a spout S into a box T., the latter having a bottom wall provided with perforations, or apertures for the downward escape of the sand and water into the receptacle. This box with a perforated bottom s erves to prevent the water and sand from discharging violently into the receptacle, and assists in causing the sand to settle to the bottom as soon as it enters the receptacle. In other words, and with a comparatively large stream of water and sand discharging directly into the receptacle, the contents of the latter would be kept boiling, so to speak, with the result that the sand would remain in suspension and would not precipitate, but to the contrary would be carried off through the spout O with the water. The box T can be of any suitable form and construction, but the perforations1 in the bottom thereof must be of suilicient size to prevent clogging and provide a free discharge of the sand and water downward in the form of a number of small streams which will not cause a boiling action or agitation of the contents of the receptacle.
